PORTABLE X-BAY vrnw ne Box.

Application filed December-13,1924. Serial No. 765,666.

My invention relates to viewing boxes for X-ray negatives, and theobject of my invention is to produce an efiicient, simple and easilyportable Xray viewing box which may be quickly prepared for use, and maybe illuminated by plugging in on any usual electric light circuit. A

The manner in which I accomplish my object is illustrated in theaccompanying drawings, in which:

Fig. 1. is a vertical cross section through my improved portable X-rayviewing box when set up ready for use, the protective cover plate beingremoved.

Fig. 2 is a similarview showing the device folded and the cover plate inplace.

Fig. 3 is a plan of the folding reflector which forms a part of myimproved device.

Fig. 4 is a top plan view of my device when set up as in Fig. 1.

The same reference characters refer to.

the sameparts throughout the several views.

It is to be understood that the drawings are in a certain senseillustrative only, and that many changes may be made in the devicewithoutdeparting from the spirit of this invention. For instance, thereflector may be hingedly attached togthe tray like portion or base ofthe device if desired.

- Referring to the drawings, B is the traylike back which forms thesupporting base of the device when set up as 1n Fi 1, and which isdesigned to contain the 0 din reflector B, when the device is fold orpacked as in Fig. 2.

Attached to t e base B by means of suitframe like member F, the openmgthrough which is-closed by a translucent material, such as ground glass,G, upon which the picture to be viewed is to be laid. Beneath, part G,is a sheet of semi-transparent material, such as tracing cloth, T. Aprotecting cover plate C, adapted to protect the part G from accidentaldamage when the device is not in use, is detachably fastened in theframe F in any suitable manner, here illustrated as by the dowel d, anda spring bolt 85.

The ends-of a substantially U-shaped supportin bracket U are 1pivotallysecured to the si es of the frame and the cross-bar U of the bracket,fitting into suitable illustrated. A

of the carrying and spaced from the ,the light which emanatesfromnotches in the sides of the base B, holds the frame Fin proper angularelevation with reference to the base B. (See Fig. 1.) The cross-bar Ualso provides a support for a lamp socket S, adapted to receive a lamp17, adapted to illuminate the interior of the box. I prefer to use adaylight lamp for this purpose, and the bracket should be soproportioned, and the socket so located on the cross arm thereof thatthe lamp when in place therein will be on aline with the center of theopening through the frame F, when the device is set up ready for use.

A length of cable is attached to the socket, and in this cable ispreferably incorporated a suitable switch and plug whereby the same maybe connected to-any usual lamp socket and the circuit controlled. Theseparts being standard and this general arrangement universal, they havenot been shown.

The manner in which m device is packed when dismounted is clear y shownin Fig. 2 of the drawings. Before packing the de' vice the lamp is to beremoved from the socket, the reflector is than folded and laced in thetray-like base B, and the brac et U swung up and the parts foldedtogether as storage place for the lamp and the necessary cord, switch,plug and so forth, is provided by attachi at the sides handle H which islocated at the center of the end of the frame F, a box or boxes T.

Some suitable means, staple, are provided for B and F in closed A deviceof this kind constructed sub stantially as illustrated and described, isquite sim 1e and readily portable. The placing o the lam substantiallycentral with the frame an providing a reflector which will concentratepractically all of the lamp directly against or through the,semi-transparent member T and the translucent member G, insures theelficient illumination of all parts of a plate placed u on the member Gto be viewed. The use 0 daylight lamps as the source of light, a groundglass as a base for the plate to be viewed to rest on, and asemi-transparent curtain between the lamp and the ground glass, producesan aprelation to each other.
